PAL has performed several tests on the camera control system, focusing on the detection, identification and selection processes at various speeds of the conveyor belt, for different volumes of material.
The pilot plant has been tested with one camera first (test with virgin wood with the addition of different content of plastics, and test with recycled wood with the real content of laminated wood), and then with both cameras (upper and lower) to verify the synchronism between them and the performance of the industrial PC in the computation.
Other kind of tests have been done: tests with small lamps to reduce size and power absorption, and tests with reduced ROI (region of interest of spectrum) to increase the camera frame rate.
The tests demonstrated that the pilot system is able to remove up to 95% of plastic impurities from the recycled wood.
